Nudzejma, Full-Stack Web Developer

Experience

Software developer, Virgin Pulse

01/03/2022 – Current 
Primarily working as a full-stack developer on micro-services based on Java/Kotlin language.
In this role my main focus was on:

• Getting a better understanding of these languages by learning new things and actively doing PR reviews.
• Diving more into back-end technologies and started working with Lombok and SQL H2O migrations.
• Getting familiar with AWS (Amazon Web Services) (mostly: IAM with SG, SNS, SQS, EC2, ElasticSearch, S3) and Terraform.
• Understanding and tuning existing CI/CD, adding GitLab jobs (pipeline with new checks) and implemented SonarQube integration.
• Getting familiar with Kafka and Kafka Streams. Using an ES sink connector via Kafka Streams.

One of the challenges that I encountered in this role:

• Did several ES (ElasticSearch) seminars and courses to gain knowledge and improve our ES size/capacity, shards, nodes, ES querying, and Indices.
• I managed notification transport (SNS and SQS in AWS) by creating infrastructure resources in Terraform. With notification transport, I implemented a Java code that enabled uploading JSON files into the S3 bucket in AWS.
• JSON files were filled and chunked, with data pulled from ES.
